New feature: Fill Custom Columns with Story Metadata. Look in Config to set it up.

Thank you for this feature. I just started using this plugin and was trying to figure a way to fill the rating info into a custom column in calibre. Lo and behold you updated the plugin with just that feature. Thank you.

The copy to custom column feature seems to work well with the stories I pulled from fanfiction.net. At first it did not appear to work with the rating setting, however I realized that the issue was that my custom column was using a "text, but with a fixed set of permitted values" field and I did not have all of the story ratings in my list. I created a new column of just text and it imported the rating just fine after that.
